"Another reason to seek admission is the university's multinational student body. That is very important to me because I am a representative of a foreign nation myself. "
"Another reason to seek admission here is the national diversification of the student population, this will make me feel more comfortable on campus since I am a representative of a foreign nation myself."
I guess you could be struggling with the disconnect between the two sentences? Or the Another reason part, or the myself part.. anyways, here are some possible alternatives. I hope they don't skew the sentence too much:
The university's student body was another attractive factor because as a foreign student, such a diverse group of peers would definitely be a plus.
The university's diverse student body was another reason I want to attend _such_and_such_university_ because I know interacting with such a group will give me the freedom to truly learn.
Just a Question though, what's the prompt for the personal statement? If this part of the prompt fits better in context, maybe you could post the other parts too. Good luck!
